Weekend Edition'sEco-nomical Holidays series on saving money and the environment got me thinking: More than ever, music makes the perfect gift. Changes in the way music is sold have made it easy to be environmentally friendly, since downloaded music does away with plastic packaging and discs.

The most popular digital download program, of course, is Apple's iTunes. You can buy iTunes gift cards just about anywhere, but you needn't even buy the plastic card — just log on and send a load of music credit to a friend. Amazon also sells a lot of MP3s. Then there's indie-label-centric eMusic and (the now-legal) Napster and a whole raft of sites that operate on a subscription model, including Rhapsody. One great advantage of Rhapsody is that it allows you to listen to entire songs before you buy them (a feature long-overdue from iTunes).

Anyway, on to the 10th annual Director's Cuts gift guide. While we wait for Steve Jobs to post full iSamples, you can hear my recommendations in full here and buy the songs as an iTunes playlist using this link below:

The 10th Annual CD, Er, MP3 Gift Guide

The Sea and Cake is a Chicago-based band that's been around since 1993, and Car Alarm is their 2008 release. I don't know about the "alarm" part of that title, but "car" seems apt. You can imagine these breezy cuts as perfect tunes for next summer's road trip.

Longtime listeners of Weekend Edition might remember Cantinero, a.k.a. Chris Hicken -- we traveled to New York to do a story on the music he made in his apartment. Recording that way had its challenges, evidenced by the sounds of his dogs barking that ended up on his last record. He's since moved upstate to a place that offers more space for his recording equipment and lots of room for his dogs to roam. He has some solid backing musicians now, and some six drummers, including Gogol Bordello's Tamir Muskat, contribute to various tracks.

For the world music fan, here's some music from Peru by way of Canada. Appropriately, that makes for tropical rhythms backed by some chilled-out beats. The Vancouver-based trio Pacifika is fronted by Peruvian-born singer Silvana Kane, joined by a Canadian guitarist and bass player from Barbados. This is a track from their debut album, Asuncion.

Brazilian singer Luciana Souza celebrates the power of the human voice with an interesting project called Moss. Souza says she ran into fellow singer Peter Eldridge on a train in New Jersey a few years ago, and they began conspiring to bring together. That group of innovative vocalists grew to include Theo Bleckmann, Kate McGarry and Lauren Kinhan. In this cut we hear a beautiful arrangement of the Neil Young song "Old Man."

For the classical music fan, here's a music suggestion featuring the violin sonatas of Robert Schumann. German violinist Carolin Widmann plays violin accompanied by Hungarian pianist Denes Varjon. It's on ECM Records, which was founded in 1969 as an avant-garde jazz label and remains famous for its pristine recordings. That same recording sensibility is applied to their classical releases, which you can hear in this "Allegretto" movement from the Sonata No. 1 in A Minor.

This past year saw the tragic death of innovative Swedish jazz pianist Esbjorn Svensson, who died at the age of 44 in a scuba accident. Years ago, his trio E.S.T. came to NPR's Studio 4A and showed off their unique performance methods -- they plucked strings inside the piano, and ran the sound of both piano and standup bass through electronic processing. This kind of experimentation and improvisation is showcased on Leucocyte, a jam session recorded between gigs in Australia. Little did they know it would end up as the group's final release.
